路由切换对于面向连接的通信来说是一个重要问题，需要在一定时间内保持路由。本文提出了一种新方法来缓解主机迁移率较高的网络中的路由切换问题。通过监视消息的信号强度，接收传入消息的路由中的主机可以检测本地可能的路由波动。当平均信号强度下降到危险水平时，接收消息的主机将向路由源主机发送预警消息。如果源主机能够在本地找到更稳定的路由，它就会适配一条替代路由，并在原路由真正发生故障之前完成适配过程。如果路由源主机无法在本地适配新路由，则源主机将被迫考虑整个网络来寻找新路由。
Route switching is an important issue to connection-oriented communication that needs to maintain a route for a certain period. This paper suggests a new approach to ease the route switching problems in a network with higher migration rate of hosts. By monitoring the signal strength of messages, a host in a route that receives an incoming message can detect possible route fluctuations locally. As the average signal strength declines into a dangerous level, the host that receives the message will send an advance-warning message to the route source host. If the source host can find more stable routes locally, it will adapt a substitute route and will complete the process of adaptation before the breakdown of the original route actually occurs. If the route source host cannot adapt a new route locally, the source host will be forced to search for a new route by considering the entire network.
